A simple surface-level scratch can be judged using your fingernail. If your nail is unable to catch it then it can be removed using a special rubbing compound. This is done by first, washing the affected area properly using car soapy water and then cleaning it with a microfiber cloth. Now using a buffing pad a small amount of rubbing compound is applied. The compound is aggressively rubbed in on to the scratched area in a circular motion by applying little pressure. The objective is to remove a bit of scratched clear coat. The whole process is repeated again and again. Finally, the area is washed and air-dried.
